In the current study, three types of common plants, namely Tomato (Solanum lycopersicum), Cucumber (Cucumis sativus) and Orange (Citrus sinensis) were obtained and screened for their polyphenol oxidase (PPO) activity, Among the three plants, Solanum lycopersicum was chosen with maximum enzymatic activity, it had the highest productivity of the enzyme (23733 U/mg protein).The PPO from Solanum lycopersicum

Carbon monoxide (CO) contamination represents a major global concern. This study aimed to detect the concentration of CO, emitted from various vehicles exhausters which are important contributors in deteriorating air quality. The data was collected throughout the heavy parking period at Al- Jadyria campus in Baghdad University. The vehicles were classified into two main groups according to the type of gasoline they are filled with; including premium leaded and leaded free gasoline (PLG and LFG respectively), as well as engine size, odometer, brand and model. Seven low duty vehicles for each engine size (<1.6 to >2.0) liter were selected randomly. A portable gas detector type (Altair® 4X) was used to measure exhausted emiss

The current study was included the use of okra seeds (Abelmoschus esculentus) for preparation of Defatted Okra Powder (DOP), Okra Protein Concentrate (OPC) and Okra Protein Isolate (OPI). Three methods were used to identify the best one for protein concentrate preparation . The concentrate with 72.1% protein was prepared by removal of seed peel, ground, defatting and treated with ethanol. The optimum conditions for  protein isolate preparation were 1:40 (water: DOP), extraction time of 75 minutes, extraction pH 9.0 and the precipitation pH was  4.0. This study also investigated the chemical composition to products that were 50.8,72.1,91.2% protein ,0.88,0.86,0.32 % fat ,8.45,9.94,2.67% ash and 35.23,12.37,3.26%

Red meat production is an essential and important in the amount of livestock production part and contribute to livestock about 22% of the value of agricultural production, except fish in Iraq over the medium term from 2013 to 2009,The red meat and meat products of are consider good foods with a high nutritional value because they contain vitamins, proteins, fats and minerals .So it requires such a study to estimate the function supply red meat to a statement most influential variables in the supply quantity of red meat during the period 1995-2013 It is clear from the results that the rise in red meat prices by 1% leads to increase the quantity supplied of red meat increased by 0.403%, while the increase of chicken meat prices by

The wheat crop of the most important strategic food grain crops as it's source of food for more than (35%) of the world's population, particularly in third world countries from which Iraq.. This study deals with the subject of measuring the economic efficiency of rain-fed farms wheat in the region in order to identify the most important factors affecting the level of efficiency, in addition to estimating the size of the resources generated economic efficiency overall. It was obtained preliminary data from field sources by relying on a stratified random sample of wheat farmers included (225) farm productive season (2013-2014) in the province of Sulaymaniyah. It has been measuring the Total economical efficiency in

This research was aimed to identify the most important factors affecting the production of wheat crop in Iraq for the period 1990-2016. The ARDL model was used to interpret the relationship between the dependent variable and the independent variables in the search. The research concluded that the continuous increases in the population would lead to increases in support to the wheat crop due to the increase in consumer demand for this crop, which prompts the state to try to encourage producers to achieve increases in production. The research also found that increases in inflation led to higher levels of support because rising inflation rates unfairly distribute income among individuals, therefore the government is

A study was conducted to specify mutations of the internal transcribed spacer (ITS)  in the nucleotides of nuclear ribosomal DNA (nrDNA) and their molecular relationship with heterosis exhibited by the six A- lines and three R-testers of sunflower.

This study was initiated to examine the tomato-infecting viruses belonging to the Tobamovirus and Potexvirus genera in Iraq. Field observations and surveys were carried out for three successive cropping seasons (2020/21 to 2022/23) in selected tomato production areas. The purpose was to identify the main viruses associated with tomato epidemics and assess the impact of different tomato cultivars on disease occurrence. A total of 700 tomato leaf samples were collected from seven governorates (Baghdad, Diyala, Babylon, Najaf, Kerbala, Nasiriya, and Basrah) and tested using pathogen-specific immunostrip kits. The survey showed a presence of Tomato brown rugose fruit virus (ToBRFV), Tobacco mosaic virus
